I didn't get on with Easyfits either - at the moment I'm finding our Wee Notions super reliable, no leaks at all and Lili wears them for 3-4 hours. You can get some good deals on the classifieds, or if you go for fairly basic ones with no embroidery or extras they're pretty cheap new!
I think the problem is the leg gape as the space is very wide when compared with my ittis. Might have to sell them on or keep them and see if they fit any better once he's older. I love the colours and so want to love the nappy but can't be bothered with changing bubs every time he wears one
